Please read carefully the instructions on page 3.

We would like to assess the stage of your physical development using the drawings on the next pages. These show various stages commonly used by doctors to assess the growth and development of boys.

We need to know which drawings most closely match your stage of development at the moment.

Not all teenagers follow the same pattern of development.

Just pick the stage that is closest, based on both the picture and the description.
